Star Fox Adventures has a file in it called GAMETEXT.BIN that contains all of the dialog subtitles and menu text for the entire game.
Including a
gigantic portion of unused text left over from its days as Dinosaur Planet. Over half of Dinosaur Planet's (very, very different) storyline is still in GAMETEXT.BIN, as is text telling you to connect things like the N64 Expansion Pak, etc. Since I am lazy, I'll just copy and paste what I wrote about it on
GiantBomb's Wiki:
Dinosaur Planet's plot involved the war between a dragon-like race called "Kamerians", and the Krazoa. The Kamerians had existed on Dinosaur Planet for centuries, and were originally worshiped as Gods by the lesser species. The Kamerians created the powerful and dangerous Spellstones. According to the Krazoa, the Kamerians intended to use the Spellstones to destroy Dinosaur Planet, and a war began between the two species over their creation. Though, to the player, the Krazoa are introduced as "Peace Spirits" that bring life to the planet, characters throughout the game hint that they have a more sinister purpose. A boss in Star Fox Adventures described simply as a "Mutant" was originally named "Drakor", a key character to Dinosaur Planet's storyline, and General Scales' father. Before fighting Drakor in Dinosaur Planet, he would relay a key piece of dialog to the player: "Do not believe everything the Krazoa have told you. We Kamerians did not start the Great War." He declares that defeating the Krazoa Spirits is the key to destroying Dinosaur Planet, and that there is no task more important to him.
It would eventually be revealed that by joining all Krazoa Spirits together at the Krazoa Shrine (originally called "Warlock Mountain" in Dinosaur Planet) they would form the ultimate weapon in the galaxy. Not enough of the Dinosaur Planet script remains to describe what happens after that.
